Suppose a UDP client wants to communicate with a UDP server, so it will send a request to the UDP server (using the UDP socket opened at client's end), now this will reach the UDP module at the UDP server, where UDP module will identify the UDP service using the port number and will send that request to that UDP service/server.
List of TCP and UDP port numbers - Wikipedia This is a list of TCP and UDP port numbers used by protocols of the Internet protocol suite for operation of network applications.. The Transmission Control Protocol (TCP) and the User Datagram Protocol (UDP) needed only one port for full-duplex, bidirectional traffic. The Stream Control Transmission Protocol (SCTP) and the Datagram Congestion Control Protocol (DCCP) also use port numbers. What is UDP? | Cloudflare What is User Datagram Protocol (UDP/IP)? UDP is a communication protocol used across the Internet for especially time-sensitive transmissions such as video playback or DNS lookups. It speeds up communications by not requiring what’s known as a “handshake”, allowing data to be transferred before the receiving party agrees to the communication. UDP communication is blocked by the Windows Firewall rule
What’s the Difference Between TCP and UDP?
UDP sockets or Datagram sockets are different from the TCP sockets in a number of ways. The most important difference is that UDP sockets are not connection oriented. More technically speaking, a UDP server does not accept connections and a udp client does not connect to server. Test connection to udp Port using telnet command
Attributes. UDP is a simple message-oriented transport layer protocol that is documented in RFC 768.Although UDP provides integrity verification (via checksum) of the header and payload, it provides no guarantees to the upper layer protocol for message delivery and the UDP layer retains no state of UDP messages once sent. For this reason, UDP sometimes is referred to as Unreliable Datagram
